VALVE.

Specification of Letters Patent.

Patented Dec. 11, 1917.

Application tiled March t5, 1916. Serial No. 81,573.

To all whom it may concern.'

Be it known that l, @Hannes E. Sonnen,

a citizen of the United States, residing' at 'the outlets.

Another object ot the invention is the provision ot a valve including a casing having; inlet and outlet openings termed therein, and a hollow plug; valve having' openings in its wall correspondinnl to the inlet and outlet openings of the casing3 whereby the tlow et fluid through the inlet and outlet open ings can be easily controlled.

t turther object ot' the invention is 'the provision of a valve such as above described which will be comparatively simple and inenpensive to manufacture, reliable and eilicient in use requiring,1 but few parts and which is easily operated.

l/lith the above and other objects in. view the present invention resides in the novel features ot construction, formations, combi nations, and arrangements ot parts to be hereinafter more fully described, claimed,

and illustrated in the accompanying draw` ing` forming a part of this application, it being understood in this connection that various minor changes in the details of construction, can be resorted to within the scope ot the appended claim without departing1 trom the spirit of the invention or sacriiic ingr any of the advantages thereof,

ln the drawing:

hignre l is a top plan view ot the invention showing the inlet and outlet pipes broken oft".

Fin. 2 is a horizontal sectional view showing the inlet and both outlets in open posi tion.

Fig. 3 is a similar view showingq the inlet and horizontal outlet in open positions, and the vertical outlet closed.

lligj. et is a similar view showing,r the inlet and vertical outlet in open positions and the h crisol/ita l outlet closed.

Fig. 5 is a. vertical sectional view taken at right angles to Figs. 2. 3 and il showing the valve in a position similar to that shown in Fin'. 2.

6 is transverse sectional view taken tlirougrh the .major end ot' the plus' which is ren'ioved trom the casing.

lF is a similar view taken through the minor cud thereof.

`ltete.rring` to thc accompanying drawing by correspending1 characters oi reference throughout the several views, the numeral 8 designatesin general iny improved valve, which consists et a casing` 9 chainbered as shown at l0 to receive a tapered hollow plug il. j The casing Si is provided with oppositely entendine` side nipples l2 and 13 and an upwardly extending; vertical nipple ll for connection respectively with the inlet pipe l5 and outlet pipes l@ and l?.

Passages lli, l@ and .20 lead from the open ends of the nipples lil, i3 and 14E, and communicate with the central chamber l0 oi the casing".

Une end ot the valve casing 9 is formed with a circular bead or tlanpge 2l provided with graduation marks 22 to register with the projections or lingers 23 formed upon the major end' of the plug ll which is liltewise provided with a handle 24. by means ot which the plus' 1l can he rotated for a purpose to be later' explained.

As shown in the accompanying1 drawing the handle Q-'lis preterably cast integrally with the plugr ll which is provided at its opposite or minor end with a threaded stem. 25 proj ecting a suitable distance beyond the opposite end ot the casing 9 for engagement with a nut QG hy rneans et' which the plug is held in position.

The minor end ot the plug il entends slightly beyond the adjacent ends ot' the casingr 9 and seats within a recess 27 termed in one side et a washer it@ whicln when the nat 26 is tightened is forced against the plug and all adjacent portions of the casing 9 sealing the latter against leakage.

The major end of the hollow plug 11 is provided with openings 29 and 30 arranged at approximately ninety degrees relative to each other and adapted to register with the before described passages 19 and 20 in the casing.

rlhe opposite or minor end of the plug is provided with openings 31, 32 and 33 which are ladaptedv to register with the inlet passage 18 of the casing.

The openings from 29 to 33 inclusive obviously communicate with the passages from V18 to 20 inclusive and by the proper manipnlation or' the handle 24, as will be here-inafter more fully described, control the flow of the fluid into the casing 9 through the inlet 15 and out through the outlets 1G and 17.

The operation oit' the device is as follows: VVhenit is desired to open the inletand both of the outlets the handle 2a is moved to the position shown in Figs. 1 and 2. -When in this position it will be apparent that the inlet passage 18 ot' the casing registers with the opening 32 in the valve and further that the passage 19 in the casing registers with the opening 30 in the valve while the passage 20 in the casing registers with the opening 29 in the valve. This permits the water to pass into the casing through the inlet pipes 15 and out again through the outlet pipes 16 and 17.

When it is desired to shut oii' the iiow of water through the pipe 17 the valve 2.1i is :given a quarter turn in the direction of the :arrow shown in Fig. 1.

"This operation moves the opening 29 in the plug into registration with the opening 19 and likewise moves the opening 33 into registration with the passage 18 which permits the water to flow into the Casing through the pipe 15 and out again through ,the pipe 16, thus closing the passage 20 and shutting olf the flow of water through the pipe 17.

A quarter turn from the initial position shown in Figs. 1 and 2, in the direction ot the arrow shown in Fig. 2, nieves the plug l1 so that the opening 31 will register with the passage 18 and the opening 3() with the passage 20. This shuts oll' a flow o t water through the passage 19 and pipe 1G and permits the water to ilow into the easing through the pipel 15 and out through the pipe 17.

VJ hen the plug is in the position shown in Fig. d a quarter of a turn in the direction indicated by the arrow shuts otl` not only the outlet passages 19 and 2O but likewise the inlet passage 18.

From the loregoing description taken in connection with the accompanying drawing it will be manifest that a valve is provided which -will fulfil all of the necessary requirements oi" such a device,

Having thus iully described the invention, what I claim as new angl desire to protect hy Letters Patent is:

1n a valve such as described, the combination of a casing having a central tapered recess formed therein, said casing having an inlet and an outlet passage leading from the opposite sides thereof to the opposite ends of the tapered recess, a hollow plug valve disposed within said recess and having three inlet openings provided therein for registration with the inlet opening in said casini?. and two outlet openings formed in one end thereof for registration with the outlet opening, said inlet and said outlet openings in the valve being each disposed in the same horizontal plane and being` so positioned that h v a partial turn of said valve any one ot said inlet openings can be brought into reg` stration with the inlet passage of the casino and one of the outlet openings brought into registration with the outlet passage. or said passages can be entirely cut oit.

Signed at lVashington, in the District oli Columbia this 25th day of February, 1916.
